静态代码块，构造代码块，构造方法的执行顺序

结论：

a.父类的静态代码块
b.子类的静态代码块
c.父类的构造代码块
d.父类的构造方法
e.子类的构造代码块
f.子类的构造方法

演示

父类：

package t1;/** * Created by Administrator on 2017/6/4. */public class ClassA {    private static String name;    private String pwd;    {        System.out.println("这是父类的构造代码块");    }    static{        name="classA";        System.out.println("这是父类的静态代码块");    }    public ClassA(){        System.out.println("这是父类的构造方法");    }}

子类

package t1;/** * Created by Administrator on 2017/6/4. */public class ClassB extends ClassA{    private static String nameB;    private String pwdB;    {        System.out.println("这是子类的构造代码块");    }    static{        nameB="classB";        System.out.println("这是子类的静态代码块");    }    public ClassB(){        System.out.println("这是子类的构造方法");    }}

测试方法

package t1;/** * Created by Administrator on 2017/6/4. */public class Test {    public static  void main (String [] args){        new ClassB();    }}

结果：
